The electro-lnagnet- 7: now being ener gized, it operates the alarm circuit C, the electric horn H remaining in operation until the operator removes the switch S to the position in which the circuit C is closed through the contact armature d. The contacts 2 and i operated by the spring controlled armature t can engage a am in the recess provided. in the locking disk 10, the'clutching electro-magnets w remain energized and cause the selecting disk to be taken around by the primary dis diiring a-complete' revolution, that is to say until the armature 25 comes to lie again in front ,of the recess provided in the locking disk to, the contacts t, it being then automatically disengaged from each other, thereby interrupting thecircuit of the clutching electro magnets; m and thus stopping the further rotation of the selecting disk.

Before arriving again in front of the contact c, the bell crank lever contacts gg which a have been operated, under the control of the clectro-magnet e are forced back to their original positions by means of the promoting rod 0 which lies in the path of the arms g of said levers and causes them to be moved back as they pass in front of it.

The device hereinbcfore described may be used as calling devices in ordinary or wireless telegraphy or as selective devices for closing a particular circuit in preference to other circuits such' as the fuse circuit of a memos mine or'explosive eharge particularl selected among other mines or exp osive char es.
